The end of btrfs

Well that's the end of btrfs for me; barely a month in it's shat itself and taken my /home with it.

I've lived this long without metadata checksum and snapshot...

I was able to extract a list of trees, even though it wouldn't mount, even with the various recovery options, using

Root Sony Z3 compact with Lolipop (Android 5.1)

This keeps all your data and most settings intact, so you can use your phone as you do it (though it will spend a lot of time 'optimizing apps') or stop and go out :-)
You don't need to unlock the boot loader, so the camera quality stays awesome, and you get all the bundled apps, along with the Google ones.

Install Kingroot (I used 4.8) and let it root your phone.
